Definition
Pricing is charged per input token at $42 per Btok ($0.042 per Mtok). Output tokens are free, so the cost of a request is dominated by how much state and how many questions you send.
TypeSafe's product page frames that as a 238x lower input price than Claude Fable 5.1 and claims 193.6x faster and 444.6x cheaper than LLMs on its own workflows. Those multipliers are vendor-run comparisons rather than independent measurements.
